Matter &The Atom
The term matter describes all of the physical substances around us: your table, your body, a pencil, water, and so forth
Matter is made of atoms
Models are often used for things that are too small or too large to be observed or that are too difficult to be understood easily
A closer look at quantum mechanics:
This atom has lost an electron. Now it has one more proton than electron.
One more proton means one more positive charge.
This makes the total charge of the atom POSITIVE.
This atom has gained an electron. Now it has one less proton than electron.
One less proton means one less positive charge.
This makes the total charge of the atom NEGATIVE.
